The AD9850BRSZ is a really cool device that can do a lot of things! It uses DDS technology, a high-speed D/A converter, and a comparator to make a frequency synthesizer and clock generator that you can program digitally. In this guide, we’ll take a closer look at the AD9850BRSZ and explore its main features, how it works, and the different ways it can be used.

Overview of AD9850BRSZ

The AD9850BRSZ is a really cool device that combines a bunch of different technologies to make a really versatile frequency synthesizer and clock generator. It uses something called DDS technology, which is pretty advanced, along with a high-speed D/A converter and a comparator.

The AD9850BRSZ is great at generating signals with high efficiency and precision thanks to its advanced DDS technology. This device uses a high-performance D/A converter and comparator to ensure precise waveform synthesis. By integrating this, you can be sure that it will work at its best and operate smoothly without any issues.

The AD9850BRSZ is really good at creating high-quality sine waves that can be adjusted to specific frequencies and phases. Sine waves have the ability to act as a frequency source on their own or can be transformed into square waves to be used in agile clock generator applications. With this device, you can program the frequency and phase characteristics of the output to have more control and adaptability in different applications.

The AD9850BRSZ is great for applications that need accurate and steady frequency synthesis because it can create programmable analog output sine waves that are very pure. The AD9850BRSZ is a great choice for generating signals, modulating frequencies, or creating clocks. It’s reliable and high-performing, making it perfect for demanding applications like telecommunications, test and measurement, and scientific research.

High-Speed DDS Core

The AD9850BRSZ has a really cool feature called high-speed DDS (Direct Digital Synthesis) core that makes it work better and do more things.

The AD9850BRSZ has a DDS core that enables you to have accurate frequency control with its 32-bit frequency tuning word. When you use a 125 MHz reference clock input, this 32-bit tuning word allows for an impressive output tuning resolution of 0.0291 Hz. With this level of resolution, you can be confident that the frequency synthesis is accurate and can be finely adjusted to meet the needs of even the most demanding applications.

In addition, the AD9850BRSZ has the ability to produce output frequencies that are as high as half of the reference clock frequency. This means that the maximum output frequency that can be achieved is 62.5 MHz. The wide range of output frequencies is perfect for various applications that need flexible frequency synthesis.

Another cool thing about the AD9850BRSZ is that it can quickly change the output frequency digitally, even without synchronization. The AD9850BRSZ is pretty cool because it can generate up to 23 million new frequencies every second. This means it can quickly and easily change frequencies, which is helpful for making real-time adjustments.

The AD9850BRSZ is a great choice for applications that require accurate frequency control, like generating signals, frequency modulation, and flexible clock generation. With the high-speed DDS core, engineers and designers can achieve accurate and flexible frequency synthesis in their systems. This is made possible by its impressive output tuning resolution, broad frequency range, and rapid frequency transitions.

Phase Modulation and Square Wave Generation

The AD9850BRSZ has five bits of digital control that allow for exact phase modulation and different amounts of phase shifting. This function lets users change the phase of the output waveform to suit their needs. This is useful for communication systems and signal processing, for example.

The AD9850BRSZ also uses a high-speed comparator to make a square wave output with low noise. Because it can do this, it can be used as a flexible clock generator where accurate and stable square wave outputs are needed for timing and synchronization.

Overall, the AD9850BRSZ’s phase modulation and low jitter square wave generation make it more useful as a frequency oscillator and clock generator. These features make it easier for engineers to control the phase of their designs and make sure they run on time.

Loading Formats

The AD9850BRSZ can be written in two different ways: bytes in parallel and bytes in serial.

Iteratively loading an 8-bit control word and a 32-bit frequency setting word is how the parallel load format works. The control word handles phase modulation, power-down enablement, and loading format, while the frequency tuning word gives exact control over frequency. The AD9850BRSZ can be easily programmed by using this file.

There is also serial loading, which lets you program the chip by sending a 40-bit serial data stream on a single pin. By sending control and frequency tuning information in order, this simplified method makes setup easier.

Engineers can easily program the AD9850BRSZ to meet the needs of their applications because it can be loaded either in parallel or in series.

In short, the AD9850BRSZ can be programmed in a variety of ways because it allows both parallel byte loading and serial loading. The AD9850BRSZ is easy to set up for the best performance, whether the user is using the repeated parallel load or the streamlined serial load.
